Observational variables included live percentage, number of leaves, leaf length increase, number of buds, and number of root, root length and environmental observation. The results showed that the combination treatment of growth media for the growth of Coelogyne pandurata orchid had significant effect on the number of shoots and had no significant effect on the percentage of live, number of leaves, the increase of leaf length, number of root and root length. Based on the research, it can be concluded that all combinations media provide live percentage of more than 80% and the combination of coconut fiber and fern gives the best result the number of buds that is 2,56 buds.Keywords: Acclimatization, Coelogyne pandurata Orchid, Combination of Media
